You are investigating the report of a UFO landing in an isolated portion of New Mexico, and encounter a strange object that is r

SIZIF [17.4K]

Answer: 5 m

Explanation:

We have the following data:

$I_{1}=0.11 W/m^{2}$ is the intensity of the sound at 7.5 m from the source

$r_{1}=7.5 m$ is the distance at which the intensity $I_{1}$ was measured

$I_{2}=1 W/m^{2}$ is the intensity of the sound at $r_{2}$ from the source

We have to find $r_{2}$

Since the object is radiating the signal uniformly in all directions, we can use the <u>Inverse Square Law for Intensity:</u>

$\frac{I_{1}}{I_{2}}=\frac{r_{2}^{2}}{r_{1}^{2}}$

Isolating $r_{2}$ :

$r_{2}=r_{1}\sqrt{\frac{I_{1}}{I_{2}}}$

$r_{2}=7.5 m\sqrt{\frac{0.11 W/m^{2}}{1 W/m^{2}}}$

$r_{2}=2.48 m$ This is the distance at which the intensity is the "threshold of pain"

Now, we have to substract this value to $r_{1}$ to find how much closer to the source can we move:

$r_{1}-r_{2}=7.5 m - 2.48 m=5.02 m \approx 5 m$

When an ocean plate converges with another plate, what is created on the seafloor at the line of convergence?

drek231 [11]

When two oceanic plates meet, the process of subduction occurs. During this, the denser plate slips underneath the lighter one, creating a subduction zone. In these subduction zones, a trench is formed.
Trenches are deep crevices on the ocean floor and are home to many different marine species.<span />
